In this video from the Nagios World Conference, Janice Singh from CSC presents: Visualization of Monitoring Data at the NASA Advanced Supercomputing Facility.
See how the NASA Advanced Supercomputing used an in-house solution to display data in a completely different way. The NAS facility includes several supercomputers, archival storage systems, Lustre filesystems, and NFS filesystems as an integrated system. If any one piece is down, it can affect the whole facility. Therefore, the visualization provided with Nagios did not meet the needs of NAS, so another layer was added to create a quick view of the system status.
